<pre wrap="">Yes it does. If you want to avoid this extra copy, and have a
pre-existing output array, you can do:
np.add(a, b, out=c)</pre>

And is there a temporary copy when using inplace operators like:<br>
<br>
<meta name="qrichtext" content="1">
c = a.copy()<br>
c += b
<meta http-equiv="Content-Type" content="text/html;
charset=ISO-8859-1">
<style type="text/css">
p, li { white-space: pre-wrap; }
</style><br>
<br>
Is there a temporary (c+b) array which is then assigned to c, or is
it really an inplace assignment as the operator += would suggest ?<br>
